If the warning A7AB Extension I/O configuration failure is shown,
• make sure that the value of parameter 15.02 is CMOD-02.
• set the parameter 15.01 value to CMOD-02.
You can now see the parameters of the extension module in parameter group

The PTC input is reinforced/double insulated. If the motor part of the PTC sensor and wiring
are reinforced/double insulated, voltages on the PTC wiring are within SELV limits.
If the motor PTC circuit is not reinforced/double insulated (ie, it is basic insulated), it is
mandatory to use reinforced/double insulated wiring between the motor PTC and CMOD-
02 PTC terminal.
